I have the gist of things, maybe I can even write one up. There are too many classes spoken and unspoken still, perhaps we could simply have a written description by the players of their chosen jobs.
Like:
-------
Name: Light Yagami Kira
Race: Human, eastern
Level: 15
Classes:
Occultist (10)
Occultists are magic casters who draw their techniques from an eldritch source, be it a pact with a voice in their heads, a membership to a dark cult which patronizes some unknown entity or an arcane tome with nothing but names in it. They specialize in dealing necrotic damage over time and stacking these at range through quick casting, however they have little to no defense even compared to other spellcasters.
Diplomat (5)
Diplomats are courtesans, courtiers and intermeditiaries between conflicts. They rely on a combination of good looks, manners and refined words to persuade others to their cause. They get a bonus to social situations and can redirect threat with their skills, protecting party members or avoiding damage by doing so. Reccommended for those with high CHARISMA.
-------
Then if someone's class description and related skills get too ridiculous (etc I CAN DO EVERYTHING WELL), we know that we're not dealing with a roleplayer but a mary sue instead.
